Second Upgrade Gadget for HSX1001
“HSX1001 C03M02G”
Acoustune introduces the HSX1001 C03M02G, a new upgrade set for the modular TWS earphone HSX1001 Jin. This combo includes a German silver acoustic chamber and a wired module, giving users more options for customizing their listening experience.

■ Modular Design for Wired & Wireless Use

The HSX1001 Jin features a modular design where the driver unit (acoustic chamber) and wireless module can be detached. This lets users switch between wireless and wired use, extending the earphones' lifespan and offering more versatility than typical TWS models.

■ “C:03” German Silver Acoustic Chamber

The new C:03 acoustic chamber is made of German silver—commonly used in musical instruments—for a richer and more resonant mid-to-high frequency sound.
To balance the softer bass of German silver, it uses a new dual-magnet driver with a titanium dome, delivering clear highs and punchy lows.
Compared to the original aluminum C:01, the C:03 offers a fresh and unique sound while keeping the precision build quality.

■ “M:02G” Wired Module with Pentaconn Ear Connector

Swap out the wireless module with the M:02G wired module to turn the HSX1001 into a high-quality wired earphone.
It includes a reliable Pentaconn Ear connector and comes with Acoustune’s ARC83 cable (4.4mm balanced). The module is also compatible with other Pentaconn Ear upgrade cables.
Finished in “sage green,” the design pays homage to the classic HS1503 AL model with a calm and elegant aesthetic.

■ Durable and Flexible ARC83 Cable

The included ARC83 cable is soft, tangle-resistant, and built to last.
It features a 4.4mm 5-pole balanced plug and uses Pentaconn Ear connectors for better durability and contact reliability.
The detachable cable makes replacements easy, ensuring long-term use and performance.

■ Fully Customizable System with Future Upgrades

All modules and chambers in the HSX1001 system are interchangeable.
You can use C:03 with the original wireless module (M:01) or combine C:01 with the new wired module (M:02G).
Of course, C:03 + M:02G gives you a premium wired earphone setup.
More upgrade parts are on the way, so users can keep customizing their earphones.
Each set includes a screwdriver and screws for easy part swapping—no extra tools needed.
